The CHV-THSTAT is a versatile heating and cooling thermostat with integrated humidistat designed for one- and two-stage control of forced air,
radiant, and heat pump HVAC systems. Although functional as a standalone
thermostat, the CHV-THSTAT delivers greatly enhanced functionality as
part of a complete automation system from Crestron®. Available in white,
black, or almond, the stylish wall mount design is a complement to any
The large backlit LCD display, navigable using four simple pushbuttons,
provides easy access to indoor and outdoor temperature and humidity
readings, setpoint adjustments, system mode and fan status indicators,
and setup menus. Climate control features include separate heating, cooling, and humidity setpoints with optional automatic changeover between
heating and cooling modes. Adjustable anticipators prevent overshooting
the set temperature, and continuous fan operation can be selected when
needed for increased circulation.
Automation System Integration
Multiple Crestron thermostats may be networked via Cresnet® to any 3-Series® control system, including the DIN-AP3, enabling global temperature
and humidity adjustment from any thermostat. Automation functions such
as lighting, motorized blinds, or lawn sprinklers can be accessed through
two custom remote function pages, and customized text messages can be
sent to the LCD display to provide maintenance reminders and other alerts.
Its connection to the control system also allows for full control and scheduling of the CHV-THSTAT from touch screens and computers throughout
the home, and supports extensive flexibility for integration with other
devices and systems. In the event that communication with the control
system is disrupted for any reason, the CHV-THSTAT will remain operable
to control the HVAC system.
Remote Sensors
Optional remote temperature and humidity sensors can be connected
to the CHV-THSTAT for enhanced flexibility and optimized performance.
Climate can be regulated according to an average of multiple sensors, or
the built-in sensors can be disabled entirely to allow the CHV-THSTAT to
be installed out of view. Outdoor climate can also be monitored, enabling
outdoor low-temperature compensation to prevent condensation on
windows during cold weather. The CHV-THSTAT accepts up to four remote
temperature sensors, two remote temp/humidity sensors, or a combination
of one temp/humidity and two temperature sensors.
